Among our real-time PCR instruments, the following are compatible with HRM: 7500 Fast Real-Time PCR System, 7900HT Fast Real-Time PCR System, StepOne™ and StepOnePlus™ Real-Time PCR Systems, ViiA™ 7 Real-Time PCR System, QuantStudio® 6 and 7 Real-Time PCR Systems, and the QuantStudio® 12K Flex Real-Time PCR System.
The instrument will need to be calibrated for HRM. This includes an HRM dye calibration and a melt curve file for data analysis. You can find the appropriate HRM calibration plate for your instrument here. For detailed calibration instructions, please refer to the HRM guides for each instrument and the appropriate software:
QuantStudio™ 3 and 5
QuantStudio™ 12K Flex
QuantStudio™ 6 and 7
7900 and 7500 SDS v1.x
We provide the MeltDoctor™ HRM dye for HRM applications. Other commonly used dyes for HRM include LCGreen® Plus, Eva Green® dye, and SYBR® Green dye.
The PCR primers need to be designed for robust performance and must be specific to the region of interest with a minimum of primer-dimers and nonspecific products. A variety of software tools are available to help design HRM primers, including Primer Express® 3.0 Software, Primer3, Primer3Plus, and Methyl Primer Express® Software for methylation-sensitive HRM analysis.
We have two options for HRM reagents. The MeltDoctor™ HRM Master Mix contains all components (excluding template and primers) formulated for superior HRM performance across a wide range of genomic targets. It is recommended for most HRM application except methylation-sensitive HRM. The MeltDoctor™ HRM Reagent Kit provides individually packaged PCR components and the MeltDoctor™ HRM Dye required for high-resolution melt analysis that is recommended for methylation-sensitive HRM analysis (as it does not contain dUTP).
We do not have any HRM calibration plates for 96-well standard blocks. To perform HRM experiments on such a system, you can instead use our MeltDoctor™ HRM Calibration Standard to create your own calibration plate.
You can use HRM to discover novel SNPs over a specific target region, or to quickly screen samples for a specific target SNP. In both cases, you can track the mutation changes by viewing the aligned melt curves.
